The Best Areas For Energy-Saving New Build Homes

Posted 25 November 2021 by Keith Osborne

New research reveals which areas see the biggest savings in energy costs in a new build home compared to an older one...

The latest research from Warwick Estates reveals how new build homes can see homebuyers cut their energy bills by as much as 60%.

Now that winter has arrived, running a home is set to become more expensive than during any other time of year due to vastly increased heating and utility bills. One of the most appealing factors of new build homes is that their increased energy efficiency means that these bills will be lower than they are for older, existing homes. But by how much?

Warwick Estates looked at the energy costs associated with running both new and existing homes on an annual basis and how the two compare to see where new build homes can save homebuyers the most on their energy bills.

In England, energy bills for an existing property cost an estimated £797 per year. For a new build property, annual energy bills cost just £390, a difference of £407, or 51.1%. New builds can save homebuyers the most on their energy bills in the North West of England, where the annual energy bill for a new build home comes in at 52.4% less than an existing property.

In Wales, heating an existing home is even more expensive at an average of £852 per year, while heating a new build in Wales costs £412, a saving of £440 or 51.6%.

On a more localised level, the list of places where there is the biggest difference between energy costs for new build homes and existing homes is topped by two London locations – Harrow and Redbridge. In both boroughs, brand new homes are 60.1% cheaper than existing properties, followed closely by Malvern Hills (59.9%) and West Devon (59%).

COO of Warwick Estates, Bethan Griffiths, commented: “The energy efficiency difference between new-build homes and older, existing properties is stark. Improved insulation technologies, better windows, smart meters, and more, all contribute to a notable saving every year.

“Not only does this increased efficiency save the homeowner and occupier large sums of cash, but it also significantly reduces the home’s carbon footprint. So there is a far wider benefit than our bank accounts alone.”

A Guide To Part Buy Part Rent
With Home Reach you buy a share of your chosen newly built home and pay a monthly rent on the part you don’t buy. Your budget will decide the size of the share you buy, rather than the size of your home. So, you might decide to buy a bigger share of a lower priced home or a smaller share of a more expensive home.
